As you fly through space, your ship’s scanners are always searching for nearby signal sources. They will appear on your Navigation Panel when your ship is within 1,000 Ls of them. Explorers are suggested to regularly check their Navigation Panel when traversing a system to perform surface scans, and report anything unusual.
While most signal sources are temporal in nature, reflecting the dynamic nature of the galaxy, a small number are persistent; they can always be found in the same place, by anyone. These are in addition to those located from Unregistered Comms Beacons.
